Picture your brand on your customers’ home screens. They open it with one tap, they’re already signed in, and your latest news reaches them as a notification instead of an email they might never open.
Getting there starts with one decision: how to build the app. Get it right, and you launch sooner and spend far less keeping the app up to date for years after launch.
Big companies land in different places. Shopify builds all of its mobile apps with React Native.
H&R Block’s MyBlock app once ran on three separate codebases, for Android, iOS and the web. The team rebuilt it with Ionic’s Capacitor.
This guide compares four ways to build an app: web apps and PWAs, native apps, cross-platform apps and hybrid apps. You’ll see how each one works, what it’s best at and what it leaves you to maintain, with a set of questions to help you choose the right one for your business.
Native, Web, Cross-Platform and Hybrid Apps at a Glance
Native, web, cross-platform and hybrid apps differ in how they’re built, where people get them and how much of the work you do more than once.
| Web app or PWA | Native | Cross-platform | Hybrid | |
|---|---|---|---|---|
| How it's built | HTML, CSS and JavaScript, running in the browser | Swift for iOS and Kotlin for Android, with each platform's own tools | One shared codebase in a framework like React Native or Flutter | Web code and native code combined, in proportions that vary by app |
| Where people get it | A link; a PWA can also be installed from the browser | App Store and Google Play | App Store and Google Play | App Store and Google Play |
| What you maintain | One web codebase | Two apps, plus your website | One app, plus your website | Web code that can be shared with your website, plus the app's native code |
| Device features | Whatever the browser allows | Full access, with new OS features on day one | Nearly full access, through the framework and native modules | The common ones, through native code and plugins |
| Performance | Browser speed | The best | Close to native | Close to native for most business apps, weaker on heavy graphics |
| Best suited to | Reach, search traffic and testing an idea | Games, AR and apps built around the device's hardware | New app-first products with a custom interface | Businesses with an established website or web app |
One thing you need to understand: no app has to be fully “native”, “cross-platform” or any other label. A native app can load some of its screens from the web, and a hybrid app can draw its navigation and key screens natively, so it’s more useful to look at what you’d build and maintain with each one.

What Is a Web App?
A web app is software that runs in a browser, so people use it through a link instead of downloading anything from an app store. It can be as simple as a booking form or as complex as an online store, a banking portal or a project management tool.
Web apps are built with HTML, CSS and JavaScript, usually as one codebase that serves every device. That makes them quick to update: publish a change to your server, and everyone gets it the next time they load the page.
Spotify’s web player is a familiar example. It plays music in a desktop browser or on a phone, with nothing to download.

The browser gives a web app its reach, and it also sets its limits. Anyone with a link can use it and search engines can index it, but the browser decides which device features it gets.
On iPhone, a web app can only send push notifications after someone adds it to their Home Screen.
A web app also has no place in the App Store or Google Play, and no icon on the home screen unless someone adds one. That’s the biggest difference between a web app and a mobile app.
That difference shows up in sales, too. In our research, app shoppers converted at 1.7 to 3 times the rate of mobile web shoppers.
What Is a Progressive Web App?
A progressive web app (PWA) is a web app that people can install from the browser. Once it’s installed, it gets an icon on the home screen, opens in its own window without the browser’s toolbar and can work offline, as Google’s web.dev guide describes.
A PWA is still a web app, so the browser and operating system decide what it can do. Chrome on Android gives web apps access to Bluetooth devices, for example, while Safari on iPhone doesn’t.
A PWA can be packaged for Google Play and the Microsoft Store as well. Getting one into the App Store is harder, since Apple expects more than a repackaged website.
PWAs are a strong fit when reach, search traffic and one web codebase matter most.

What Is a Platform-Specific Native App?
A platform-specific native app is built separately for each operating system, with that platform’s own languages and tools. iPhone apps are usually written in Swift with SwiftUI, and Android apps in Kotlin with Jetpack Compose, Google’s recommended toolkit for native Android interfaces.
Building natively gives your developers the most direct control over:
- The platform’s own interface components and gestures
- Device hardware, such as the camera, sensors and Bluetooth
- Background tasks and offline storage
- Graphics, animation and heavy processing
- New operating system features, from the day Apple or Google releases them
That control comes with more work. Every feature is designed, built, tested and released twice, once for each platform, usually by two teams with different skills.
If you also run a website, that’s three products to keep in step.
Native development makes sense when the app is the product and pushes the device hard: games, camera-first tools, apps paired with Bluetooth hardware and field apps that have to work offline.
If your app does the same job as your website, as it does for an online store, two native apps usually mean far more work than you need.
What Is a Cross-Platform Native App?
A cross-platform native app is built once in a shared framework and shipped to both the App Store and Google Play. The two best-known cross-platform frameworks take different routes:
- React Native uses JavaScript and React, and its components map to each platform’s native interface building blocks.
- Flutter uses Google’s Dart language and draws its own interface, compiled to native code for each platform.
Both are proven at scale. Meta uses React Native for Facebook Marketplace and Ads Manager, and Google Pay and BMW are among the companies on Flutter’s showcase.
Cross-platform doesn’t mean you write the app once and forget about the platforms. Teams still handle each platform’s settings, permissions, testing and store releases.
React Native’s docs show how to write platform-specific code for screens that need to differ, and Flutter apps reach native APIs through platform channels.
For most new apps, cross-platform is a better route than two separate native apps, unless you need the very best performance and control on each platform. React Native and Flutter both give you one team and one app codebase for both stores.
If you have a website, the catch is that a cross-platform app is still a second product. Its code is separate from your site’s, so new features and redesigns get built twice, once for the web and once for the app.
What Is a Hybrid App?
A hybrid app combines web code and native code in one app, instead of separate codebases written only for iPhone and Android. People download it from the App Store or Google Play like any other app.
The web code runs on the device’s own browser engine, often through a WebView. The native code handles everything that makes it an app, such as the store package, the icon, push notifications and access to device features.
Hybrid apps mix the two in different proportions:
- Some are mostly web code, packaged as an app with a framework like Capacitor, which calls itself a cross-platform native runtime.
- Some are native apps that load selected screens, such as help pages or account settings, from the web.
- Others put a custom native interface, with native navigation and app-only screens, on top of a website’s underlying code.
That range is why blanket statements about hybrid quality don’t hold up. A basic website in an app shell and a custom native interface built on a site’s code are both hybrid apps, yet they feel nothing alike to the people using them.
What Hybrid Apps Do Well
Hybrid apps are at their best when you’ve already built something for the web. They let you:
- Reuse the code, design and features you’ve already built for your website or web app
- Build with web developers instead of separate iOS and Android specialists
- Ship one change to your website and your app at the same time
- Get a place in both app stores, with push notifications and device features
Web developers are also the easiest to find. In the Stack Overflow Developer Survey 2026, 62% of developers had done extensive work in JavaScript in the past year, against 10.8% for Kotlin and 5.9% for Swift.
That reuse is why Burger King chose Capacitor. It let the team bring its existing web UI library to the brand’s mobile app.
Breeze Airways built its app with Ionic, so one engineering team ships it to iOS, Android and the web from a single codebase.

Hybrid also suits ecommerce especially well. An online store’s website and app do the same core job, letting customers browse, add to cart and check out, so there’s little reason to build that job twice.
Where Hybrid Apps Need Care
A hybrid app is only as good as its web code. Slow pages and weak mobile design don’t go away inside an app, so a hybrid app built on a slow website will feel slow too.
Apps that lean hard on graphics hit a ceiling. Screens drawn with web code can’t match native views for games, augmented reality or complex animation, which is why more custom hybrid apps draw their navigation and key screens natively.
Native plugins and bridges need upkeep too. Someone has to test navigation, logins, payments, permissions and offline states inside the real app, and keep them working through every new iOS and Android release.
Apple’s review rules also apply. Guideline 4.2 asks apps to offer features, content and UI beyond a repackaged website, so a hybrid app needs app features of its own, such as native navigation and push notifications.
How to Choose an App Development Approach
The right way to build an app depends on what it has to do and what you already have, more than on any framework. Work through these questions with your team before you compare tools.
1. Do We Already Have a Strong Website?
If your website already works well on mobile, building on it saves the most work. A hybrid app can carry over your content, product catalog, accounts, checkout and integrations, the years of work that already run your business online.
A native or cross-platform rebuild gives you more control over every screen. It also gives you a second product to keep in sync with the first.
2. How Different Does the App Need to Be?
If the app is a different product from your website, with its own workflows and screens that don’t exist on your site, build it as its own app, natively or with a cross-platform framework.
If it sells the same products, shows the same content or serves the same accounts, sharing code with your site makes more sense. A hybrid app can still look and feel different from your website, with native navigation, app-only screens and push notifications.
3. Which Device Features Are Central?
Most apps rely on a handful of device features, such as push notifications, the camera, location and biometric login. Hybrid apps reach all of these through native code or plugins.
It’s a different story when the whole product depends on the hardware. Advanced camera controls, continuous background location, Bluetooth accessories, NFC, augmented reality and heavy processing on the device all get more direct control with native code.
4. Do We Need Offline Functionality?
Offline support has to be designed in, whichever approach you choose. A native app can store a lot of data on the device, but it doesn’t work offline automatically.
A PWA can cache pages and content for offline use. Live stock levels, payments and anything else that depends on your server still need a connection.
List the exact tasks people need to do offline, then check which approach handles them best.
5. Who Will Maintain It?
Every app needs work for as long as it’s live: operating system updates, store releases, framework upgrades, security fixes and testing. That maintenance adds up.
The more codebases you run, the more of that work you do. Two native apps and a website mean three sets of updates, while a hybrid app built on your website’s code keeps most changes in one place.
Which Option Fits Which Project?
Each way of building an app is the best choice for a different kind of project. This short video from our team walks through the differences between native, hybrid and web apps.
Choose a Web App or PWA When
- You need to reach people through a link, on any device.
- Search traffic and shareable pages matter most.
- One responsive experience covers what people need.
- You want to test an idea before you invest in the app stores.
Choose Platform-Specific Native When
- The app is your core product.
- Performance, hardware access or offline work is central to the app.
- Each platform’s own design and newest features justify building everything twice.
- You have the mobile teams and budget to maintain two apps.
Choose Cross-Platform Native When
- You’re building a new, app-first product for iPhone and Android.
- The app needs a custom interface with no website behind it.
- The framework and its libraries cover the features you need.
- Your team can handle platform-specific testing, releases and native modules.
Choose Hybrid or WebView When
- You already have a website, web app or online store worth building on.
- The app does the same core job as your website.
- You want your app and website to stay in step from one codebase.
- Native code or plugins can cover the device features you need.
How MobiLoud Helps You Launch Low-Effort, High-Upside Mobile Apps
If you have an established website, native and cross-platform apps share one big downside. Either way, you build a second product next to your website, with its own codebase and team, and you keep the two in step for as long as the app is live.
MobiLoud removes that second codebase. We transform your website into a custom native app, powered by the same underlying code as your website.
The app gets its own native navigation, app-only screens and push notifications, and it starts with everything you’ve already built.
Our team builds, publishes and maintains the app through every iOS and Android update, so you can go live in a few weeks and keep your developers on the work that grows your business.
TradeZing had already built a cross-platform app with Flutter, but its web platform and app were separate, and keeping both going took a lot of extra work. Its apps now run on the same code as its web platform.
"We literally had a dev team of about 30 people. We were able to cut the entire head count down to just a couple of core people working on our web tech stack."
The app’s design is yours to set. Streetwear brand Cold Culture gave its app a layout built for buying, different from its website, and the app passed 250,000 downloads without any dedicated promotion.

If your app is a new product with no website behind it, or it’s built around the device’s hardware, native or cross-platform development is still the right route.
The Bottom Line
How you build your app decides what it costs you long after launch: how many codebases you run and how quickly you can ship a change.
Choose a web app or PWA if reach and search matter most and an installed app can wait. Choose native if the app is your product and pushes the device to its limits.
Choose cross-platform if you’re building a new, app-first product for both stores. Choose hybrid if you already have a website or web app worth building on.
